NOTICE:
To achieve optimum perfor-
mance of appliance, minimize or avoid
bends in exhaust vent pipe.
CAUTION! DO NOT
use any flue restric
-
tor when venting with the DV-46DVA-GCL
adapter and LINK-DV30B kit.
This could
result in poor flame appearance, sooting,
pilot malfunction, or overheating.
Connecting the DV-46DVA-GCL Adapter to Appliance
Top Vent
• Remove top seal cap and insulation if equipped. See
Section 6, “Appliance Preparation.” Attach the DVP-
2SL to the 8 inch starting collar. Follow installation
instructions included with DVP-2SL kit. Attach the
DV-46DVA-GCL adapter to the appliance starting collar
with 3-1/2 in. self-tapping screws. See Figure 4.30.
Rear Vent
• Remove the rear seal cap and insulation if equipped.
Connect the DVP-2SL adapter to the vertically positioned
elbow. Follow installation instructions included with DVP-
2SL kit. Secure DV-46DVA-GCL adapter to DVP-2SL with
3-1/2 in. self-tapping screws. See Figure 4.30.
Connecting the LINK-DV30B to the DV-46DVA-GCL
adapter
• Insert the two sections of flexible vent pipe down the
existing chimney.
• Attach one section of stainless steel flex pipe to the
exhaust collar on top of the DV-46DVA-GCL adapter
with three screws.
WARNING! Risk of Fire, Explosion or Asphyxiation!
Do NOT connect this gas appliance to a chimney flue
serving a separate solid fuel or gas burning appliance.
• Could impair safe operation of this appliance or other
appliances connected to the flue.
• Vent this appliance directly outside.
• Use separate vent system for this appliance.
• Attach one section of flexible vent pipe to the stainless
steel flex pipe with three self-tapping screws.
• Attach one section of flexible vent pipe to the inlet collar
on top of the DV-46DVA-GCL adapter with three self-
tapping screws.
• To minimize cold air drafts, seal around the flex vents
at the damper inside the chimney with non-combustible
unfaced fiberglass or rock wool insulation.
The DV-46DVA-GCL adapter must be recessed into existing
masonry fireplace. This measurement is taken from the top
of the fireplace opening. See Table 2 and Figure 4.29.
